It carries a 0.125-inch cutting diameter with a 0.375-inch length of cut and a 0.375-inch straight-cylindrical shank, also available with a Weldon flat. At 3.0625 inches overall length, this is a regular-length tool suited for general-purpose milling operations. The centercutting geometry allows plunge cutting as well as peripheral milling. Right-hand cut and right-hand flute direction follow the standard configuration expected by most vertical milling machines and CNC machining centers. Licensed machinists and toolroom technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThe C42051 is designed for milling cast iron, non-ferrous metals, and steel. The 30-degree helix angle promotes efficient chip evacuation on these materials. The spiral flute design, combined with the centercutting tip, supports slotting, profiling, and light plunge operations. The regular length classification keeps deflection low during cuts, which is especially useful in close-tolerance work on small features where the 0.125-inch diameter would otherwise be prone to chatter or breakage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design doubles tool life before replacement is required\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry supports plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes clean chip evacuation on steel, cast iron, and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with Weldon flat option for positive tool holding\u003c\/li\u003e\n  \u003cli\u003eUncoated HSS construction — resharpenable and compatible with standard HSS grinding wheels\u003c\/li\u003e\n  \u003cli\u003eRegular length keeps tool rigidity high, reducing deflection on small-diameter cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for standard ER collet chucks, Weldon-style side-lock holders, and set-screw end mill holders accepting a 0.375-inch shank diameter. Suitable for use in vertical milling machines, knee mills, and CNC machining centers. Primary workpiece materials are cast iron, non-ferrous metals, and steel as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Always power down the spindle and confirm zero rotation before changing tooling. Seat the shank fully into the holder and torque the retention screw or collet nut to the tool-holder manufacturer's specified value. Inspect the cutting edges for chips or wear before each use, particularly on a small-diameter tool like this where edge damage can lead to sudden breakage under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C42051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720794014002,"sku":"C42051","price":59.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e839d1a0651941aa7f6ff47bc8d95fc4.jpg?v=1788569258","url":"https:\/\/voomisupply.com\/products\/cleveland-c42051-square-end-mill-0-125-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
